摘要: Azimuthal correlations have been studied in heavy ion reactions over a wide range of beam energies. At low incident energies up to 100 MeV/nucleon where collective effects like the directed sidewards flow are generally small, azimuthal provide useful tool determine reaction plane event by [1]. In energy regime BEVALAC (up 1 GeV/nucleon for ions) particular emission patterns, i.e. nucleons and light nuclei with respect plane, associated so called squeeze out [2] sidesplash [3] effects. These interest because their sensitivity equation state at high baryon density which is build during collision process [4]. Angular distributions similar observed pions SIS Darmstadt [5, 6] as well from EOS — collaboration [7]. Recently also sideward was measured kaons [7, 8]. However, origin signal case produced mesons thought be different nature than that nucleon [9, 10].
